My invention hasreference torec'eptacles for liquids and particularlyto' means for.

siphoning the liquids therefrom.

' It is a purposeof my invention'to provide 5 a siphoning device capableof association 1 with various forms of'liquid'receptacles by which thewithdrawalof -liqi iid'; from; a'

The lower endrof:the tubeis formed with notches" 25 which serve to maintain the tube 1end openi even when resting on the -b'ottom"7 of a receptacle so as toinsure the sagejof water intofthetube.

upper end of alcoil ed contractile spring '32 is hooked over-the upperend of theitubing 29, itsll ower end being likewise hooked to i .0 theupper' 'end of a, valve 'stemj 33Ecarrying *a conical shaped valve 34L;formed of rubber v or other suitablematerial, andaclaptedjinlitselevated position to close thelower fend of "the tuloe29.- To insureatight seat. fort -the .95 it valve; the edge'of the lower end of the V 1tubing is "taperedpr gbev-ele'd as indicated" at '35. The stem 33:constitutes part of a single length of wire which is benti'atits pointof c0nnectionwith-the lower end of: 106 1 the stem to form a horizontalportion 36 which forms a support for a disk shaped washer 37. The washer37- is designed to form a relatively large seat for the valve 34 so asto prevent cutting of the rubber of which the valve is formed. From thehorizontal portion 36 the wirev is extended upwardly to provide avertical portion 38 which terminates in the lateral extension 39, theextension being doubled back upon itself and extended to form a closedloop 40" of sufhcient diameter to be freelysl dable upon the tubing '29.7

The extension 39, constitutes, an. operating either of a pair of lips 41to retain the valve in open position against the closlng action of thespring 32. The lips 41'are formedby inturning ends of a bifurcatedextension '42 2 formed at the lower end of a vertical ex- 42 isbifurcatedfor the purpose of receiving [the vertical portion 38 of thevalve supporting frame and in a marine-into secure the frame againstrotative movement on 1 the tubing, yet allowing'suflicientdateral niovef'ment of the'extension 39 to engage beneath thelips .41 in latchingthevalve in open position. It will, of course, be understood that movementof the valve 34 to open position is against the tensionjof the spring32, and consequently when the extension .39 is vided with acord K bywhich it can be suspended froma support S suchias a nail.

'The bag B is providedwith the usualspout '1 adapted to be closed by astopper. in the applied position of the siphon device, thestopper C isremoved-to permit extension of: the tubing'2l into the bag and to allowthe stopper 18 to seat within the spout and thus close the latter.

The long arm l6, the tubing 21, and the pipe 22 all coact to formtheshort'leg of the siphon device, while the short arm 17, the tubing 27,and the pipe 29 coact to form the long leg of the siphon. Vhth the short;leg within the bag B and the long leg disposed exteriorly of the bag,the siphon device'is operable in the following manner:

Assuming that 'the' bag is filled with water, water can be ejected fromthe bag through the device by first, opening the valve 34 and thencompressing the'bag to exclude a r from the siphon device when'thesiphon action will be initiated. Water entering thepipe 22 is filteredby the screen 24, and

the water discharging from the pipe 29 can be received in a cup or othersuitable receptacle as will be understood, the flexibility of the tubing27 permitting the pipe 29 to be moved to any desired position.

In operating the siphon device the groove l9vadmits air to the bagtoutilize its pressure in continuing the siphoning operation EOHtinue.Upon closing the valve the water discharge is discontinued as will beunder- ;stood, and by virtue of the fact that the arm adapted'to'begripped in moving the valve 34 to open position and to engage valve isurged to closed position, the possibility. of accidental ejection ofwater from the bag is prevented.

It will be appreciated that by means of my siphon device water can beejected from the bag while thelatter is in vertical position thuseliminating the necessity of tilting the bag. 'The water discharged fromthe bag is withdrawn from the bottom where the water is the coolest, thetube 22, by. reason of its'weight retaining the suction end of thetubing at thebottom of the baggf Although I' -have' ,herein" shown anddescribed only one form of siphon device embodying my invention, it isto be understood that various changesv and modifica tions maybe madeherein without departing from the spirit of the invention and the spiritand scope of the appended claims.
